ATTACHMENT FOR MATCHING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 429,170, dated June 3,1890.

Application filed December 31,1889- Serial No. 335,560. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES P. FLANDERS, a citizen of the United.States, residing at Parishville, in the county of St. Lawrence and Stateof New York, have invented a new and useful Attachment forlVlatching-ltlachines, of which the following is a specification.

This invention is an attachment for matching-machines; and among theobjects in view are to provide a cheap and simple device constructed andadapted to flatten the boards or lumber squarely upon the base or tableof the machine at the same time that the lumber is operated uponby thecutter-heads, whereby an even uniform tongue and groove are formed atthe opposite edges of said lumber. It is well-known among wood-workersthat especially hard wood when thoroughly seasoned is difficult toevenly match, owing to the fact of its disposition to curl or bend, andfor the purpose of thoroughly flattening the lumber at the pointsthereof as they are operated' upon by the cutters of the matchingmachinefriction-shoes have been employed. 2 5 These, however, were open tograve disadvantages, arising from the fact that in order to compress thelumber perfectly flat upon the table they must exert a comparativelyimmense pressure which, while efficient, if 0 the pressure be sufficientyet was extremely damaging to the machinery by which the lumber is fedto the cutters, the strain thereon being excessive.

The object, therefore, of my invention in 3 5 addition to the above isto increase the pressing-power exerted upon the lumber, so as to insureperfectly-truematchin g and at thesame time to almost wholly obviate anyadditional strain upon the feed mechanism and to yield- 0 ingly mountthe compressing agent, so as to readily pass over all obstructions of asolid nature which would otherwise tend to a clogging of the machine.

WVith the above general obj sets in view the invention primarilyconsists in a roller located between the two cutting-heads of themachine and yieldingly mounted in position, and secondarily in otherfeatures of construction hereinafter described, and particularly 5opointed outintheclaims.

Referring to the drawings, Figure 1 is a perspective of a portion of amatching-ma chine table provided with an attachment constructed after myinvention. Fig. 2 is alon gitudinal section of the same, on an enlargedscale.

Like numerals of reference indicate like parts in all the figures of thedrawings.

1 represents the stationary section of an ordinary matching-machinetable, and 2 the movable section, which, as is usual, is adapted bysuitable mechanism to be adjusted to and from the first-mentionedsection, and each of said sections upon their inner upper edges isprovided with a track or way 3.

4 represents the vertical spindle or arbors. upon each of which ismounted a cutter-head 5, of the usual construction, one adapted to forma tongue and the other a groove, each spindle being mounted in one ofthe sections 1 or 2, and having the cutting-periphery of its headprojecting into the adjacent way 3.

At the front end of the table there is mounted a pairof oppositestandards 6, one upon each of the sections 1 and 2, said standards beingoppositely perforated, as at 7 and in the same and projecting at eachside of the standards is a sliding rod 8.

9 represents an inverted-U-shaped frame, the terminals of which haveopenings for the reception of the ends of the rod 8, and the upperportion of said frame is provided with a longitudinal slot 10. At theopposite end of the bed or beyond the cutters there is mounted a similarpair of standards 11, hav- 8 5 ing openings 12, in which is mounted atransverse rock-shaft 13.

14: represents a lever or rock arm provided at its rear end with anopening 15, which receives the shaft 13 between its bearings 12, andsaid rock-arm is provided with a setscrew 16, which adjusts the sameupon the shaft at any point between the bearings of the latter. Theforward end of the rock-arm is provided with a head 17 and the same is 5transversely slotted, as at 18, and loosely receives the rod 8. A pin 18projects upwardly from the head 17 and passes through the longitudinalslot 10 of the U-shaped frame 9, and above the same is provided with ahead 19, to prevent a withdrawal of the upper end of the pin from theslot.

20 represents a coiled spring of a sufficient rigidity, and the same ismounted between the head 17 and a vertically-opposite point of the frame9, the spring encircling the pin and serving, when not otherwiseinfluenced, to draw the head 19 of said pin upon the upper surface ofthe frame 9.

Intermediate the rod 8 and shaft 13 the rock-arm ll is provided with anelongated vertical slot 22, extending from near one end to the other ofthe arm, and passing through the walls of the slot directly between thecutters 5 and their arbors is a transverse shaft 23, and mounted forrotation upon the shaft is a pressure-roller 24, or, if desired, morethan one roller may be employed in aceordance with the width of thelumber to be operated upon. The roller is removable, and varying sizesmay be substituted for the above purpose and to agree with the distancebetween the cutters, whereby a strip of lumber, as 25, inserted betweenthe standards 6 and under the roller, will have its oppositelongitudinal edges pressed perfectly fiat and uniformly presented to thecutters, thereby insuring a perfect tongue and groove of the lumber. Byreason of the coiled spring it is apparent that a sufficient tensionwill be exerted upon the lumber to flatten the same, as beforementioned, and the rock-arm being yieldingly pressed will givesufficiently to any stubborn obstacle to prevent a choking or cloggingof the feeding mechanism, and the consequent stoppage of the machine.

It is apparent that the details of the inven tion may be modified andaltered in various ways, that will readily present themselves to theminds of persons skilled in wood-working machinery, and in lieu of thespring and as a well-known equivalent therefor, a weight may besubstituted, and also other accessories necessary to the substitution.

Having described my invention, what I claim is 1. In a matching-machine,the combination, with the opposite adjustable table-sections andopposite cutters, one mounted over each section, of opposite pairs ofstandards arranged at opposite sides of the cutters, a standard of eachpair being located on a table section and each of the standards beingprovided with bearing-openings, a rock-shaft .mounted loosely and forlongitudinal movement in the rear pair of standards, a crossrodsimilarly mounted in the front standards,

a rock-arm spring-pressed and mounted on the rock-arm and provided atits front end with a slot for the passage of the rod, substantially asspecified.

2. In a matehing-machine, the combination,

with opposite adjustable sections and a cutter mounted over each, of astandard mounted on each section in rear of each cutter and oppositeeach other, and provided with bearing-openings, a rock-shaft mountedloosely in the bearings and so as to permit of a separation of thetable-sections, a spring-pressed rock-arm projecting from the shaft, anda wheel journaled in the arm between the cutters, substantially asspecified.

In a matching-machine, the combination, with the base or table, theopposite cutters, and their spindles, of a pair of standards arranged atone side of the cutters, a rockshaft journaled in the standards, arock-arm mounted on the rock-shaft and extending between the cutters, aroller journaled on the rock-arm between said cutters, a head formed onthe opposite end of the rock-arm, standards arranged at each side of thesame, a rod passed through the standards and through a slot in the head,a frame mounted on the rod and extending over the head and having aslot, a pin projecting through the slot, and the coiled springencircling the pin and bearing against the frame and head, substantiallyas specified.

4. In a matching-machine, the combination, with the opposite adjustabletable-sections and the opposite cutters located in the same, of oppositestandards having bearingsin their upper ends, a standard being locatedupon each of the table-sections, a rock-shaft loosely mounted in thebearings of the standard, a rock-arm having an opening for the receptionof the rock-shaft, and a binding-screw for sccuring the same rigidlythereto, said arm terminating at its opposite ends in atransverselyslotted head, a wheel mounted upon the arm between its endsand opposite the cutters, opposite standards arranged at each side ofthe head of said arm and provided with bearings, a transversely-movablerod mounted in the bearings and having its ends extending beyond thesame, a U-shaped frame having its terminals provided with openings forthe reception of the ends of the rods and provided with a longitudinalslot in its upper end, a headed pin projecting from the head of the armsand projecting through said slot, and a coiled spring encircling the pinand interposed between the head and frame, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signaturei n presence of two witnesses.
